DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Hereinafter, a detailed description is made for embodiments of the present invention using some drawings. A component part, block in a flowchart, and the like with an identical mark functions in the same way, and thus description thereof may be omitted if previously mentioned.

First Exemplary Embodiment

FIG. 1 is a system block diagram of an information processing system according to the first exemplary embodiment. This system includes electronic apparatus 11, router 12, server 13, and external apparatus 14. Electronic apparatus 11 is an electronic apparatus to be connected to a network, such as a computer, a videocassette recorder, a refrigerator, a television set, a set top box (STB), a microwave oven. Router 12 connects electronic apparatus 11 to the Internet, performing route control, network address translation (NAT), and the like. Server 13 stores an operation information control table including one or more operation information control records including operation information for electronic apparatus 11. Server 13 is connected to the Internet. External apparatus 14 exists at a remote location from electronic apparatus 11. Although external apparatus 14 is preferably a mobile terminal, it may be fixedly installed at home or in an office. External apparatus 14 is connected to the Internet with or without wires.

FIG. 2 is a block diagram of the information processing system according to this embodiment. Electronic apparatus 11 includes operation information acquirer (hereinafter, acquirer) 1101, operation controller (hereinafter, controller) 1102, and operator 1103. Server 13 includes operation information control table storage (hereinafter, storage) 1301, operation setting information receiver (hereinafter, receiver) 1302, operation information updating part (hereinafter, updating part) 1303, and transmitter 1304. External apparatus 14 includes external information storage (hereinafter, storage) 1401, setting information acceptor (hereinafter, acceptor) 1402, operation setting information transmitter (hereinafter, transmitter) 1403, receiver 1404, and annunciator 1405.

In electronic apparatus 11, acquirer 1101 acquires operation information that is information with which electronic apparatus 11 operates, from server 13. Operation information includes, for example, operation commands such as for turning on the power, turning off the power, reserving video recording, and setting information to be set to electronic apparatus 11. If electronic apparatus 11 is a videocassette recorder or the like, with a video recording function, the command for reserving video recording serves many uses. The setting information refers to a broadcast area code with which electronic apparatus 11 receives broadcasts, and communication setting information such as a POP address and DNS address with which electronic apparatus 11 communicates with an external apparatus. Here an external apparatus is, for example, another device on the Internet. Electronic apparatus 11, if equipped with a tuner and a function for receiving broadcasts, refers to a broadcast area code to set frequencies and names of broadcast stations to each channel of the tuner. This enables electronic apparatus 11 to receive broadcasts. In addition, “acquire” here includes a case where electronic apparatus 11 passively receives operation information and a case where electronic apparatus 11 actively retrieves operation information. Timing when acquirer 1101 acquires the operation information is not especially limited. Preferably, acquirer 1101 regularly acquires the operation information; however, acquirer 1101 may acquire the operation information when triggered by a user, or when notified by server 13. Acquirer 1101 is usually composed of a wireless or wired communication device (a modem and its driver software, etc.) and control software for the above-mentioned operation. Here, hardware (i.e. electronic circuit) may be used instead of the software. Acquirer 1101 may be composed of a device for receiving broadcasts instead of a communication device.

Controller 1102 directs so that electronic apparatus 11 operates according to the operation information acquired by acquirer 1101. Timing when controller 1102 directs is not especially limited. In addition, timing when controller 1102 directs can vary depending on the contents of operation information. For example, if the operation information is a command for video recording, controller 1102 directs so that electronic apparatus 11 starts video recording at the start time for video recording included in the command. If the operation information is a command for turning on the power, controller 1102 may direct so that the power is immediately turned on (main power ON). If the operation information is communication setting information, controller 1102 directs so that electronic apparatus 11 communicates according to the communication setting information being set, when a direction to start communications is made from a user. Still, if an operation direction after acquiring the information is not given immediately according to the operation information acquired by controller 1102, the operation information is accumulated in a storage medium which is not illustrated. Although this storage medium is preferably a nonvolatile one, a volatile one is accepted. Controller 1102 may be implemented with hardware although usually implemented with software.

Operator 1103 performs various types of operations, which vary depending on what electronic apparatus 11 is. For example, if electronic apparatus 11 is a videocassette recorder, operator 1103 functions, for example, for turning on/off the power, recording/replaying video. Operator 1103 is usually composed with software and hardware.

In server 13, storage 1301 stores an operation information control table. The operation information control table includes one or more operation information control records each including an external apparatus identifier, an electronic apparatus identifier, and operation information. The external apparatus identifier is information for identifying external apparatus 14, and the electronic apparatus identifier is for identifying electronic apparatus 11. Although storage 1301 is preferably composed of a nonvolatile storage medium, a volatile one is also acceptable.

Receiver 1302 receives from external apparatus 14, operation setting information including the external apparatus identifier, the electronic apparatus identifier, and the operation information. Receiver 1302 is usually composed of a wireless or wired communication device; however, a device for receiving broadcasts can be used.

Updating part 1303 updates the operation information control table in storage 1301 according to the operation setting information received by receiver 1302. This “update” includes adding a record to the operation information control table, and correcting a certain attribute value in the record. Updating part 1303 is usually composed of a central processing unit (CPU, not illustrated) and software for operating the CPU; however, it may be composed of hardware (an electronic circuit).

Transmitter 1304, when a process in server 13 is completed, transmits the circumstances to external apparatus 14, and also transmits the operation information to electronic apparatus 11. Transmitter 1304 may be integrated with receiver 1302.

In external apparatus 14, storage 1401 stores the external apparatus identifier. Storage 1401 is preferably composed of a nonvolatile storage medium; however, a volatile one may be used. Here, the external apparatus identifier may be whatever information to identify the external apparatus. For example, it is an IP address of the external apparatus, MAC address thereof, or phone number of the external apparatus if it is a mobile phone.

Acceptor 1402 accepts input of setting information including the electronic apparatus identifier and operation information. The setting information may be either information input by a user or one transmitted from another apparatus. That is to say, acceptance of input includes reception of information. Acceptor 1402 is usually a keyboard driver, a remote control driver, or the like. That is to say, acceptor 1402 is composed of software and hardware accepting information input from an input device such as a keyboard or a remote controller. However, acceptor 1402 may be a communication device for receiving information or broadcast receiving device.

Transmitter 1403 transmits to server 13, the external apparatus identifier stored in storage 1401, and operation setting information including the setting information received by acceptor 1402. Timing when the operation setting information is transmitted to server 13 is not especially limited. Usually, the operation setting information is transmitted to server 13 according to directions by a user of external apparatus 14. Here, external apparatus 14 may regularly transmit the operation setting information to server 13. Transmitter 1403 is usually composed of a wireless or wired communication device; however, a broadcasting device may be used.

Receiver 1404 receives process results in server 13.

Annunciator 1405 annunciates results received by receiver 1404 to the user via voice and/or display.

Hereinafter, a description is made for the operation of the information processing system. First, an operation of electronic apparatus 11 is described referring to FIG. 3.

(S301) Acquirer 1101 judges if it is the time to acquire from server 13, operation information that is information with which the electronic apparatus operates. For example, acquirer 1101 tries to regularly acquire the operation information. If it is the time to acquire, the processing goes to S302; otherwise, returns to S301.

(S302) Acquirer 1101 connects to server 13.

(S303) Acquirer 1101 acquires the operation information from server 13.

(S304) Controller 1102 judges whether or not the operation information acquired at S303 is to be immediately executed. There are various methods for this judgment. For example, the operation information may include an operation start time. In such a case, controller 1102 checks the present time and judges that the command in the operation information be executed, if the present time agrees with or is past the operation start time included in the operation information. Meanwhile, the operation information may not include an operation start time. In such a case, electronic apparatus 11 retains an operation start time (operation start timing) corresponding to the command included in the operation information, and controller 1102 may judge that operation be started at the operation start time. When judged to be immediately executed, the processing goes to S305; otherwise, to S306.

(S305) Controller 1102 directs so that operator 1103 operates according to the operation information, and so operator 1103 operates according to the operation information.

(S306) Acquirer 1101 accumulates the operation information acquired at S303. Here, the operation information accumulated is executed at the predetermined execution time or timing. In other words, the command included in the operation information is executed.

In FIG. 3, electronic apparatus 11 regularly acquires the operation information, where the timing and algorithm to acquire operation information is not especially limited. In addition, when electronic apparatus 11 acquires the operation information from server 13, electronic apparatus 11 usually requests server 13 to transmit the operation information. Server 13 transmits the operation information to electronic apparatus 11 according to the transmission request.

Next, a description is made for an operation in which server 13 receives and accumulates operation setting information from external apparatus 14, referring to FIG. 4.

(S401) Receiver 1302 judges whether or not the operation setting information including an external apparatus identifier, an electronic apparatus identifier, and the operation information has been received from external apparatus 14. If operation setting information has been received, the processing goes to S402; otherwise, returns to S401.

(S402) Updating part 1303 judges whether or not the operation setting information received at S401 is correct information, by the external apparatus identifier and the electronic apparatus identifier included in the operation setting information received at S401. If correct, the processing goes to S403; otherwise, to S405.

(S403) Updating part 1303 accumulates the operation setting information received at S401. Here, “accumulate” means, for example, “add” a record to the operation information control table stored in storage 1301. In addition, “accumulate” means, for example, “update” a record in the operation information control table stored in storage 1301. In other words, updating part 1303 changes one or more attribute values included in a record.

(S404) Server 13, via transmitter 1304, transmits to external apparatus 14, information showing that the process has been normally completed. Such information is, for example, stored preliminarily in server 13.

(S405) Server 13, via transmitter 1304, transmits to external apparatus 14, information showing that external apparatus 14 is unable to access server 13. Here, such information is, for example, stored preliminarily in server 13. In FIG. 4, the operation to transmit messages from server 13 at S404 and S405 to external apparatus 14 may be dispensed with.

Next, a description is made for an operation in which server 13 transmits the operation information according to a request from electronic apparatus 11, referring to FIG. 5.

(S501) Server 13 judges whether or not a transmission request for the operation information was made from electronic apparatus 11. If a transmission request has been made, the processing goes to S502; otherwise, returns to S501.

(S502) Server 13 judges whether or not electronic apparatus 11 that has made a transmission request is a correct electronic apparatus based on the transmission request at S501. This judgment is, for example, made with the following method. The transmission request has an electronic apparatus identifier. Then, if the electronic apparatus identifier included in the transmission request is stored in the operation information control table included in server 13, the electronic apparatus that has made a transmission request is judged to be a correct electronic apparatus. Otherwise, the electronic apparatus that has made a transmission request is judged to be an incorrect electronic apparatus. If electronic apparatus 11 that has made a transmission request is a correct electronic apparatus, the processing goes to S503; otherwise, goes to S504.

(S503) Server 13, via transmitter 1304, transmits the operation information to electronic apparatus 11.

(S504) Server 13 transmits, via transmitter 1304, an error message to electronic apparatus 11. Still, the error message is preliminarily retained, for example, by server 13. However, in FIG. 5, the operation to transmit the error message is not essential.

Next, a description is made for an operation in which external apparatus 14 transmits the operation setting information to the server, referring to FIG. 6.

(S601) Acceptor 1402 judges whether or not input of the setting information including the electronic apparatus identifier and the operation information has been accepted. If the input of setting information has been accepted, the processing goes to S602; otherwise, returns to 601. Here, “accept input of the setting information” refers to accepting a series of input, for example, including accepting a command to transmit the setting information to server 13.

(S602) Transmitter 1403 acquires the external apparatus identifier stored in storage 1401, and transmits to server 13, the external apparatus identifier and the operation setting information accepted at S601, which includes the setting information.

(S603) Receiver 1404 judges whether or not receiver 1404 has received the process result in server 13. The process result refers to information showing whether or not the operation setting information transmitted at S602 has been correctly processed in server 13. If the process result has been received, the processing goes to S604; otherwise, returns to S603.

(S604) Annunciator 1405 outputs the process result received by receiver 1404 at S603.

Here, in FIG. 6, the processes of receiving and outputting the result at S603 and S604 may be dispensed with. In such a case, receiver 1404 and annunciator 1405 are not particularly needed.

Hereinafter, a description is made for a concrete operation of the information processing system according to the embodiment. FIG. 7 is a block diagram of a concrete information processing system. The information processing system includes STB 11A, STB 11B, air conditioner 11C, router 12, server 13, and external apparatus 14. Here, the identifier, “ID”, for STB 11A is “1,” and its name is “my STB.” “ID” of STB 11B is “2,” and its name is “my son's STB.” “ID” of an air conditioner is “3,” and its name is “air conditioner in the living room.” Still, the global IP address allocated to router 12 is “132.182.5.10”. STB 11A, STB 11B, and air conditioner 11C are located at home and connected via router 12 to the Internet. Further, external apparatus 14 is a so-called mobile phone.

Next, FIG. 8 shows an example for the operation information control table retained by server 13. The operation information control table includes an operation information control record including the following attribute values: electronic apparatus identifier, name, operation information, external apparatus identifier, and polling result. The electronic apparatus identifier is composed of a global IP address and identifier (ID). The electronic apparatus identifier is information for identifying an electronic apparatus. Here, a global IP address and ID identify an electronic apparatus. The global IP address is an IP address for accessing router 12 from external apparatus 14 and server 13 therewith. The ID is information for identifying an electronic apparatus connected to router 12. The name is an appellation (a colloquial term) given to each electronic apparatus, with which a user identifies an electronic apparatus. The external apparatus identifier is information for identifying an external apparatus, where in this case, it is a phone number of a mobile phone. The polling result is information showing whether or not electronic apparatus 11 (STB 11A, STB 11B, or air conditioner 11C, in this case) has acquired operation information. If the polling result is “0,” it shows electronic apparatus 11 has not yet acquired operation information; if “1,” already acquired. The polling result is information showing that the operation information has been transmitted from server 13 to electronic apparatus 11, also called operation information transmission history information. In FIG. 8, the operation information of electronic apparatus 11B whose name is “my son's STB” shows that it has no data. That is to say, electronic apparatus 11B with “my son's STB” is registered; however, it isn't set with the operation information. Meanwhile, for electronic apparatus 11A with “my STB” or the like, the operation information is set. The operation information of “my STB” is “power ON, video recording ch. 140, 19:00-21:00.” This operation information is to direct as follows: turn on the power of “my STB” to record the broadcast of channel 140 from 19:00 to 21:00.

In the above-mentioned condition, operation setting information shown in FIGS. 9A through C is input from external apparatus 14, which is a mobile phone, and is transmitted to server 13. First, external apparatus 14 accesses server 13 to notify of transmitting operation setting information. In this case, the information including the phone number of external apparatus 14: “090-1111-2222” is transmitted from external apparatus 14 to server 13. Next, server 13 receives information including “090-1111-2222,” and acquires all information with names corresponding to the external apparatus identifier “090-1111-2222” from the table in FIG. 8. Then, server 13 transmits the information with the names acquired to external apparatus 14. Next, external apparatus 14 receives the information with the names transmitted from server 13, to display a menu. An example of this menu is shown in FIG. 9A. The information for button “End” composing the menu in FIG. 9A may be transmitted from server 13, or may be preliminarily retained by external apparatus 14. Next, the user of external apparatus 14 selects, for example, the menu entry “(2) my son's STB” from the menu in FIG. 9A. Next, external apparatus 14 displays a screen (panel) linked to the menu entry “(2) my son's STB” as shown in FIG. 9B. The information for composing the menu in FIG. 9B may be transmitted from server 13, or may be preliminarily retained by external apparatus 14. Next, the user of external apparatus 14, viewing the screen shown in FIG. 9B, inputs operation information as shown in FIG. 9C. FIG. 9C shows that the user of external apparatus 14 has checked the box “power ON,” and thus the operation information includes information for “power ON.” FIG. 9C further shows that the user of external apparatus 14 has checked the box “video recording,” and thus the operation information includes information for “video recording.” FIG. 9C still further shows that the user of external apparatus 14 has input channel “18”, start time “10:00”, stop time “12:00,” and thus the operation information includes information for ch. 18, 10:00-12:00.” That is to say, the operation information having been input in FIG. 9 is information for “power ON, video recording ch. 18, 10:00-12:00.”

FIG. 10 shows a structure of the operation setting information. The operation setting information includes an external apparatus identifier, ID, and operation information. The phone number of external apparatus 14 is substituted for the external apparatus identifier. The phone number of external apparatus 14, which is a mobile phone, is preliminarily stored in external apparatus 14. The ID is information for identifying a target electronic apparatus to be controlled with operation information. The ID is determined, for example, when a menu entry in FIG. 9A is selected. That is to say, the ID is maintained corresponding to the menu entry in FIG. 9A. The ID corresponding to the menu entry “(2) my son's STB” in FIG. 9A is “2.” The operation information is, for example, the information input from the panel in FIG. 9C. Consequently, the setting information including the operation information input from external apparatus 14 in FIG. 9C is a value set as shown in FIG. 11. Then, the setting information in FIG. 11 is transmitted to server 13.

Next, server 13 receives the operation setting information shown in FIG. 11. Then, server 13 accumulates “power ON, video recording ch. 18, 10:00-12:00” as a set of attribute values of operation information corresponding to the external apparatus identifier “090-1111-2222” and ID “2.” The above-mentioned operation updates the operation information control table in FIG. 8 as shown in FIG. 12.

Next, STB 11A, STB 11B, air conditioner 11C, or router 12 in FIG. 7 regularly operates to acquire operation information by means of polling server 13. Consequently, STB 11A and the like acquire each corresponding operation information from the operation information control table in FIG. 12 to execute and/or accumulate it. Then, the attribute value of the polling result corresponding to a part of operation information acquired by the electronic apparatus is updated from “0” to “1” in the operation information control table in FIG. 12. That is to say, updating part 1303 also updates operation information transmission history information (polling result), when operation information is transmitted to an electronic apparatus. FIG. 13 shows the operation information control table with the polling result being updated.

According to this embodiment described hereinbefore, when operation setting for an electronic apparatus at home, connected to the Internet is performed, for example, from an external apparatus such as a mobile phone, the electronic apparatus is not accessed from the external apparatus directly, but via a server, and thus security is retained.

In this embodiment, the description is made taking a global IP address in IP version 4 as an example of a part of information composing the electronic apparatus identifier. However, the electronic apparatus identifier may be whatever information as long as it enables the electronic apparatus to communicate with a server and the like, such as a global IP address in IP version 6. In addition, the electronic apparatus identifier especially may include the host address in an IP address in IP version 6. This situation also may be applied to other embodiments.

The description is made assuming that external apparatus 14 is a mobile phone, and the external apparatus identifier is a phone number of the mobile phone. However, external apparatus 14 may be a desktop computer, portable laptop personal computer, or the like, and the external apparatus identifier may be whatever information as long as it can identify the external apparatus. For example, the external apparatus identifier may be a global IP address in IP version 6, or the like. This situation also may be applied to other embodiments.

Further, the operation of electronic apparatus 11, external apparatus 14, and server 13 described in this embodiment may be described in software to control general-purpose devices. Such software may be distributed, for example, by means of downloading the software on a server. Further the software may be distributed with a storage medium such as a CD-ROM. This situation also can be applied to all other embodiments.

Second Exemplary Embodiment

FIG. 14 is a system block diagram of an information processing system according to the second exemplary embodiment. The system includes electronic apparatus 141, router 12, server 143, and external apparatus 144.

(S1805) Output part 14405 outputs the status information received at S1804.

Here, server 143, when receiving the status acquisition command from external apparatus 144, judges whether or not the external apparatus is a correct external apparatus (external apparatus being controlled), from the external apparatus identifier included in the status acquisition command. If the external apparatus is a correct one, server 143 transmits, to the external apparatus, status information corresponding to the external apparatus identifier. This process is a processing of an information retrieval from a client device to a server in a server/client model in a conventional technology, and thus a detailed description is omitted.

Hereinafter, a description is made for a concrete operation of the information processing system in this embodiment. In the block diagram of the information processing system shown in FIG. 14, electronic apparatus 141 is a set top box (STB), and external apparatus 144 is a mobile phone. Video recording information is set to electronic apparatus 141 with its power ON. For example, storage 14102 in electronic apparatus 141 stores “power ON, tape loaded, video recording ch. 24, 19:00-20:00.” This status information means the power is ON, a tape is loaded, information for reserving video recording is “record a broadcast on channel 24 from 19:00 to 20:00.” Storage 14101 stores “ID=1.” Still, the status information control table in server 143 is composed as shown in FIG. 19. The status information control table in FIG. 19 includes a status information control record composed of the attribute values of an electronic apparatus identifier, a name, operation information, and an external apparatus identifier. The electronic apparatus identifier, the name, and the external apparatus identifier are the same as described in the first exemplary embodiment using FIG. 8, thus the description is omitted. In FIG. 19, the status information of the electronic apparatus whose name is “STB at home” shows that it has no data. That is to say, the electronic apparatus, “STB at home”, is registered; however, status information has not been set.

In the above-mentioned status, for example, electronic apparatus 141 regularly acquires its own status information and transmits to server 143. Electronic apparatus 141, “STB at home”, acquires the status information stored in storage 14102: “power ON, tape loaded, video recording ch. 24, 19:00-20:00,” and the ID (the electronic apparatus identifier) of electronic apparatus 141: “1.” Then, electronic apparatus 141 transmits them to server 143 via router 12. The global IP address “131.181.0.1” is allocated to router 12. Router 12 transmits to server 143, the status information and the ID transmitted by electronic apparatus 141, with the global IP address added.

Next, server 143 receives the status information: “power ON, tape loaded, video recording ch. 24, 19:00-20:00”, ID: “1”, and global IP address “131.181.0.1”. Then, server 143 judges whether or not electronic apparatus 141 is a correct device, by the global IP address and ID received. Here, the global IP address “131.181.0.1” received exists in FIG. 19, and ID “1” also exists corresponding to the global IP address “131.181.0.1”. Therefore, server 143 judges electronic apparatus 141 transmitted status information and the like as a correct electronic apparatus.

Next, server 143 retrieves the status information received to accumulate it as status information corresponding to a global IP address and an ID. FIG. 20 shows the status information control table after the accumulation.

Here, the phone number of the external apparatus 144 that is a mobile phone is “090-7777-3333.” Therefore, status acquisition command including the phone number “090-7777-3333” is transmitted from external apparatus 144 to server 143. Next, server 143 judges whether or not the phone number “090-7777-3333” is a correct (i.e. registered) external apparatus by the status information control table and others, and judges to be correct. Next, server 143 transmits to external apparatus 144, the electronic apparatus status information including the status information corresponding to the phone number: “power ON, tape loaded, video recording ch. 24, 19:00-20:00” and the ID: “1”. Then, external apparatus 144 receives the status information including the status information, “power ON, tape loaded, video recording ch. 24, 19:00-20:00”, and the ID: “1”, then outputs it. FIG. 21 shows an output example for status information in external apparatus 144.

As described above, according to this embodiment, an external server accumulates status information for an electronic apparatus at a remote location such as home, and an external apparatus such as a mobile phone acquires the status information for the electronic apparatus at home without directly accessing the electronic apparatus. Accordingly, the status information for an electronic apparatus can be acquired from an external apparatus without being externally accessed improperly.

Hereinafter, a description is made for a concrete operation of the information processing system in this embodiment. FIG. 30 shows a block diagram of the information processing system. In FIG. 30, the information processing system includes two electronic apparatuses. One is STB 221D (ID=1), and the other is air conditioner 221E (ID=2). STB 221D and air conditioner 221E are connected to the Internet via router 12. The information processing system further includes three external apparatuses 224A through 224C. Three external apparatuses 224A through 224C are all mobile phones, an external apparatus identifier, namely a phone number is allocated to each of them. The phone numbers are “090-1234-5555,” “090-2222-5432,” and “090-3333-4444,” respectively. In addition, the information processing system includes server 283 and router 12.

Server 283 stores an operation information control table shown in FIG. 31. The operation information control table shown in FIG. 31 includes operation information control records, each composed of the attribute values such as an electronic apparatus identifier, a name, operation information, and an external apparatus identifier. The electronic apparatus identifier is composed of three attribute values: a global IP address, an identifier (ID), and priority. The priority refers to information showing priority (order) of operation information (operation setting information) transmitted from the electronic apparatus identified by a global IP address and an ID. If the value of priority is “1,” the electronic apparatus has top priority, where the operation information transmitted from the electronic apparatus is always stored in server 283. The higher value of priority shows the lower order of priority. The operation information includes contents and priority. The contents refer to information showing details of the operation information. The priority refers to information showing which priority order of apparatus has transmitted the operation information shown by the contents. The external apparatus identifier includes a phone number and priority. The phone number is one for an external apparatus to identify the external apparatus. The priority shows the order of priority of the operation information transmitted from the external apparatus identified by the phone number. In the first record in FIG. 31, the apparatus with first order of priority is “STB at home,” namely STB 221D. Similarly, the apparatus with the second order of priority is external apparatus 224B with its phone number “090-2222-5432,” and the third, external apparatus 224A with “090-1234-5555.” Further, the operation information in the first record in the operation information control table in FIG. 31: “video recording ch. 10, 19:00-21:00” shows that it is the operation information transmitted from the apparatus with the order of priority “2,” namely, external apparatus 224B.

In the above-mentioned situation, a description is made for a case where external apparatus 224A selects STB 221D, also the operation information: “video recording ch. 8, 19:00-20:00,” is input and external apparatus 224A transmits it to server 283. In such a case, server 283 receives the operation setting information including the above-mentioned operation information, and the external apparatus identifier: “090-1234-5555.” Next, server 283 acquires the order of priority “3” of external apparatus 224A from the external apparatus identifier received. Next, server 283 acquires the order of priority “2” that is the counterpart of the operation information in the operation information control table. Then, server 283 compares the order of priority “3” of external apparatus 224A, with the order of priority “2” that is the counterpart of the operation information, and then determines that server 283 does not accumulate the operation information received. Then, server 283 transmits a message showing that operation information exists that has already been registered by an apparatus with higher order of priority, to external apparatus 224A identified by the external apparatus identifier “090-1234-5555.”

Next, a description is made for a case where STB 221D transmits to server 283, the operation information: “video recording ch. 41, 9:00-22:00.” In such a case, router 12 adds the global IP address “132.182.5.10” to the operation information and the like, to transmit them to server 283. Next, server 283 receives information including the above-mentioned operation information, the global IP address “132.182.5.10,” and “ID=1.” Then, server 283 acquires from the operation information control table, “priority” corresponding to a combination of the above-mentioned global IP address and “ID=1.” As shown in FIG. 31, “priority” corresponding to a combination of the above-mentioned global IP address and “ID=1” is “1.” Server 283 acquires “2,” which is “priority” that is the counterpart of the operation information in the operation information control table. Next, server 283 compares “priority=1,” which corresponds to a combination of the global IP address “132.182.5.10” and “ID=1,” and “priority=2,” which is the counterpart of the operation information in the operation information control table. Then, server 283 judges that the operation information received can be accumulated. Next, server 283 rewrites “contents” of the operation information in the first record in the operation control table with “video recording ch. 4, 19:00-22:00”. Server 283 further updates “priority” of operation information in the first record in the operation control table, to “1.” With the above-mentioned operation, operation information transmitted by an apparatus with higher order of priority is set to server 283; and with lower, not set.

Next, a brief description is made for “air conditioner in the living room,” namely air conditioner 221E. In the operation information control table in FIG. 31, “power ON, temperature 20° C.” is registered as the operation information for air conditioner 221E. In addition, “priority” in the operation information is “1.” In such a case, even if the operation information “power ON, temperature 27° C.” is transmitted from external apparatus 224C with its phone number “090-3333-4444,” server 283 does not update the operation information. The order of priority of external apparatus 224C is “2,” which is lower than “1,” which is the order of priority of the apparatus that registered the operation information “power ON, temperature 20° C.” Accordingly, server 283 does not update the operation information.

In this embodiment, both a correct electronic apparatus and a correct external apparatus can view (acquire and then output) operation information.

In the above-mentioned embodiment, server 283 stores priority information, which is information about which operation information is given priority when is receives operation information from a plurality of apparatuses. Server 283 updates the operation information control table according to the priority information and operation setting information. This enables setting of the operation information to be properly controlled by a plurality of apparatuses.

In this embodiment, the description is made that server 283 accumulates one piece of operation information for one electronic apparatus. However, server 283 may accumulate some pieces of operation information for one electronic apparatus. Such a condition also can be applied to other embodiments.

Further, in this embodiment, server 283 stores operation information for setting broadcast recording. When server 283 receives operation information for new setting of video recording from an external apparatus or an electronic apparatus, overwrite is not usually needed if the time frames in the operation information for video recording setting do not overlap. Therefore, operation information updating part 28303 in server 283 may accumulate operation information, in consideration of overlapping video recording time. This situation also applies to contents of other operation information in other electronic apparatuses. Such a condition also can be applied to other embodiments.

The above-mentioned method of information processing and controlling of each device may be described in computer programs to be executed. Such programs are stored in a storage of each apparatus, or servers 13, 143, 223, or 283 stores the programs and distributes to each apparatus via a network. Alternatively, they may be stored in other servers on a network to be distributed to each apparatus. They may be recorded on a storage medium such as a flash memory or a CD-ROM, and may be read by a reading device (not illustrated) provided in any one of the servers mentioned above.

The present invention includes an embodiment in which each transmitter, each receiver, each storage, and the like of each apparatus described above are integrated. Further the electronic apparatus and the router may be composed as a unit.
